<p>The pack (1) is intended for holding a roll (2) of aluminium or plastics foil. It has a slot (4) through which a length (2k) of foil can be taken from the pack, and a tear-off edge strip (9) along which this length can be severed. The strip carries a layer of granulated abrasive particles. The particles may consist of adhesive/bonded corundum. The gap through which the foil passes may extend to perforation lines (5) in the pack, which permit removal of a slot covering strip (4) of wall material to free the slot.</p> |
